Key Points
1. Why GFRP for roads?
- Steel corrosion in de-icing and salt environments → cracking, delamination, and increased maintenance.
- Non-metallic reinforcement is necessary for future infrastructure such as bridges, coasts, and smart roads.
- The only alternative to eliminating corrosion = GFRP rebar.
